What we offer

Luton Puf Panel Roof Sheet

Puf panel roof sheet manufacturer is a new composite panel that takes light rigid polyurethane foams as the core material and colorful steel plates or stainless steel plates as the surface material. It has many advantages, such as a low heat conductivity coefficient, good load resistance performance, a high percentage of close area, excellent flame resistance performance, and a wide scope of temperature resistance. It is mainly used in food, medicine, cold chain logistics, and other industries.

Fireproof PUF Sandwich Panel

Fireproof PUF sandwich panels are designed to be fire-resistant, which can help to improve the safety of the building.

PUF Roof Insulated Sandwich Panels

Most Popular Questions

What can we help you with today?

The sandwich panel system is a type of construction system that consists of three layers - two outer layers and a core material sandwiched in between.

The outer layers are typically made of metal, such as steel or aluminum, while the core material can be made of various materials like polyurethane (PU), polystyrene (EPS), rock wool, or mineral wool.

PU (Polyurethane) and PIR (Polyisocyanurate) are both types of insulation materials commonly used in construction. PIR offers improved fire resistance and thermal stability compared to PU, making it suitable for applications where these properties are critical.

Yes, we can walk on the roof normally after the installation of the roofing laminate.
Sandwich panels excel over steel sheets primarily due to their superior thermal insulation, enhanced structural integrity, lightweight nature, installation efficiency, design flexibility, and environmental benefits.
In recent years, it has been widely used in all kinds of industrial buildings, making the appearance of the building have a rich expressive power, the architectural effect is simple, modern, and atmospheric, reflecting the creativity of the architect, realizing the inspiration of the architect, and is widely favored by owners and architects.
For projects near the coast, it is recommended that users use steel sheets that are galvanized in their original material, with a galvanizing capacity of 180g or more, for better corrosion resistance in the special saline environment of the coast.
Different materials are used for different environments. For saline environments, a galvanized steel plate with a zinc coating of 180g is recommended, for acid and alkaline environments, an aluminized zinc plate with a zinc coating of 150g is recommended.

The main differences between PVDF and PE-coated steel lie in their durability, weather resistance, and application suitability.

PVDF coating is more durable and weather-resistant, while PE coating is more cost-effective and suitable for indoor applications.

PU (Polyurethane) foam excels in thermal insulation and is lightweight, while rock wool (mineral wool) offers superior fire resistance, acoustic insulation, and durability in harsh environments.

Non-combustible materials (Class A): are the highest fireproof grade and do not contribute to the spread of fire.

Fire-retardant materials(Class B): are designed to slow down the spread of fire and reduce its intensity.
